Matchmaking >Yes another one of these posts

How does it work? Just got tilted by my last game so i decided to just chill and not play another and further tilt. Was on a 4 game winning streak and last game I got a mid laner that was levels below everyone else in the match, like you could tell the difference in her micro and macro play. Is it matchmakings intention to tilt you after you go on a winning streak by matching you with bad teammates and a good enemy team. That in and of itself is tilting . I need answers.
